With dairies getting larger, with more and more production, it is of utmost value to minimise waste throughout production. We have only one planet to take care of, and all the waste produced has a major effect on the environment. The Nordic countries should be in a position to lead with this issue.  

Waste is unused resources from all types of production and can be categorised into unused raw material i.e. milk, refined product, water, packaging material, energy and personnel. All of these should be reviewed when considering waste and are all equally important. Through minimising the product waste of raw milk, finished product and chemicals are probably where most dairies could lessen the environmental impact and at the same time save a lot of money. This can be done by better planning throughout the facilities and systems to retain the waste product, for example, by installing modern conductivity or turbidity sensors and filtration systems product can be rescued from going down the drain. In reality, this could be as much as 6% depending on the kind of product line and facility. A biogas plant can be a supplement for the excess waste that the dairy cannot retain in any other way.
